GREEN HOUSE.

Application med February 3, 1914.

To all whom it may concern Be it known that I, WILLIAM H. LUTTON, a citizen of the United States, residing in the city of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Greenhouses, of which the following is a specification. y

My invention relates to improved green-Y transverse sectional view on an enlarged' scale of the foundation and a portion of the superimposed structure; Fig. 3 is a trans verse sectional view on line III- #-III of Fig. l, and Fig. Li-is 'a transverse sectional View on line IV-IV of Fig. 1.

Referring to"the drawings in detail, the numeral l designates a foundation wall which may be of concrete, brick, o r any other suitable construction. Upon this wall is mounted a sill 2 having depending flanges 3 and 4:. A gutter 5 is mounted upon the depressed offset surface 6 of the wall, the upper level of the flange of the gutter thus lying below the level of the sill. Drainage is provided through the agency of an inclined leader 7 passing through the wall to the interior of the greenhouse and there connecting with a .vertical leader 8. This con. struction of gutter and drain is exceedingly advantageous; first, for the reason that the depressing of the gutter below the level of the sill permits snow to lill the gutter in winter time without banking up over the glass in the side of the greenhouse and thus obstructing the light; and, second, because the use of an interior drain prevents freezing andl consequent clogging and overflow of the drain.

The' glazed portion of the greenhouse is carried by curved rafters 9 mounted upon the sill by 'means of brackets 10. These rafters are continuous, running from the sill to the portion 1l, where they are curved, and then extending in an inclined direction to the ridge, to which `they are joined in a well known manner. Each rafter supports a correspondingly curved angle iron 12 by means of a rafter back or capping 143 of M-section, which is preferably constructed of copper or some other comparatively soft metal. The use of this back or capping com` pensates for any inequalities inthe curvature of the rafter and its associated angle. The angle itself is preferably constructed of galvanized iron' and hasmounted in it a core y14: which may be constructed of cypress wood or other suitable material. This core is essentiallyvof inverted T-secfision, as clearly shown in Figs. 3 and 4,

having portions adapted to seat against theinner surfaces ofthe legs of the angle, the opposite sides of these portions being beveled or chamfered and affording a support for the glass 15, adjacent panes being separated by l.the shoulder 16, which may also carry suitable means, not shown, for i holding the glass in place. The `legs of the angle extend somewhat beyond the surfaces of the core which seat upon them, thus forming gutters 17 adapted to carry the Water of condensation down to the sill and' thus preventing any dripfroni the roof due to t'lhe condensation of moisture within 'the onse.

It will be observed that this construci tion affords a firm and yet cushioned seating for the glass, resulting 'from the use of the wood core provided with the chainfered l glass-bedding surfaces. the great strength of this construction, the rafters may be spaced at considerable intervals to form bays, as shown in Fig. l. The adjacent rafters are connected by horizontal angle irons 18 which stiii'en the entire structure, particularly A taking up Wind stresses upon the ends of the house. horizontal, longitudinal angles also act as supports for the intermediate vertical angles 19 which are identical with the angles l2 Because of These' BEST AVAlLABLE COF3` back or 'capping is associated with them. The

number of these intermediate vertical angles if) in a bay, that is, between two rafters,is dependent upon the width of the bay formed by adjacent rafters and by the width of the panes of glass. They are not primarily re quired for structural support, since the load is principally carried by the rafters. This construction is one whichentireiy avoids the nccessity'for the use of posts to support the roof, since the 'strength of the ralzters disposed on edge is adequate to support this load. Further-more, a maximum of light is admitted to the interior ol the house owing to the use of angle irons, the legs ot which are disposed at degrees to the plane of the glass. The V-construction resulting from this arrangement oli' the angles permits the rays :of light entering the house to merge, as it were,l after passing the ape); of the angles, so that no appreciable shadow is noticeable at a ny substantial distance away from the angles. The use of rafters formed of unitary bars bent on edge and disposed at .right angles to the glass also causes a minimum interference with the light and promotes the substantially uniform illumination olf the interior of the house, and consequently provides a maximum glass area, an area which is substantially much larger in proportion to the superficial arca or" the house than that afforded by any other construction oi 'ih am aware.

TWhile I have illustrated and described only one specific embodiment of my invention, I realize that it is susceptible of wide application and l do not desire to be limited to the precise 'construction illustrated and described.
